Bill,
According to the SPE home site:
------------------------------------------------------------------------
Continuous use
“MAX” mode: SSB / CW unlimited.
Automatically switches to “MID” for a while if, in “MAX”, a continuous
signal (RTTY) is transmitted.
“MID” “LOW” modes, RTTY unlimited.
------------------------------------------------------------------------
I've inquired of Bob, W5UQ, home page http://ExpertLinears.com
as to the time in MAX on RTTY before it down-switches to MID.
Since he both sells and services them I expect that he's the
best source, other than Gianfranco in Italy, to answer your question.
The 2K-FA will otherwise operate for an unlimited period of
time in MID or LOW power mode.
